The visit aimed to kick-off a new research project in collaboration with Dr. Gideon Gal and his group at the Kinneret Limnological Laboratory in Migdal, Israel. Together with Yaron Hershkovitz, an Israeli guest scientist at the University of Duisburg-Essen, the team started to identify suitable sites for fieldwork to study the pressures acting on the upper reaches of the River Jordan, before it meets Lake Kinneret (otherwise known as the Sea of Galilea). The fieldwork, which will run until June, focus on the health and diversity of aquatic invertebrates such as insects and molluscs as indicator species for the wider health of the freshwater ecosystem in response to stresses like pollution and drought (see an earlier blog on indicator species in Israel).

One major challenge for the team was to identify streams in the Jordan catchment that would not dry up completely in the hot early summer months, and so contain enough water to allow their ecological sampling to go ahead (we’ve written before about intermittent and temporary rivers here). Once identified, these streams were split in a typology similar to that used in the Water Framework Directive by their geology (largely limestone and basalt) and size.

MARS researcher Christian Feld explains more about the fieldwork and its outcomes:

“The sampling campaign in May aims to collect macroinvertebrate communities from nearly 50 different streams. For the first time, we will apply a standardised monitoring scheme in order to ensure the comparability of the results. This procedure is alike those developed to implement the Water Framework Directive in Europe. This will open the opportunity for us to consult monitoring results from other Mediterranean countries that are Member States of the European Union.

This also offers the opportunity for MARS to collaborate with the German-Israeli Foundation project, as the monitoring data analysed in both projects are similar. Thus, the GIF project directly contributes a 17th case study to the existing 16 case studies of the MARS project. On the other hand, the GIF project can benefit from the modelling methodology developed in MARS to identify and predict the effects of multiple stressors on freshwater ecology.”

We will continue to follow the progress of the team’s research and collaborations in Israel and update you with their results.

Project funding:

The GIF project (“Ecological status and ecosystem services of the Lake Kinneret catchment: setting the scene for the management of a multi-stressed region.”) is funded by the German-Israeli Foundation for Scientific Research and Development, contract No. G-1272-203.13/2014.

The MARS project (Managing Aquatic ecosystems and water resources under multiple stress) is funded by the European Union under the 7th Framework Programme, contract no. 603378.

What is The Freshwater Blog?

Features, interviews and analyses on freshwater conservation, science and policy.

For comments, ideas and submissions, you can contact us here: info [at] freshwaterblog.eu

The blog was founded and edited between 2010-14 by the BioFresh project, an EU-funded project that built a global information platform for scientists and ecosystem managers with access to all available data describing the distribution, status and trends of global freshwater biodiversity.

Since 2014, the blog has been managed and edited by the MARS project – an EU-funded project which investigates how multiple stressors affect rivers, lakes and estuaries.

The Freshwater Information Platform provides up-to-date information on freshwater science as well as an array of research resources and tools for the assessment and management of freshwater ecosystems.
